To all w llo-m, t may concern Be it known that l, lNGoLr BIRKELAND, a citizen of the United States, residing at Fort Benton, in the county oi Chouteau and State of Montana, have invented a new and useful ShockingMachine, oi which the following is a specilication.

This invention rela-tes to shocking machines.

(lne of the objects oi the invention is to provide a light; durable and inexpensive inachine, eliminating gearings, cranks, push rods and like devices which have been used in machines of this character hereto-tore devised, and which is adapted to be coupled to and actuated by any torni of grain binder.

'i still furthe-r object is to provide a machine which will gather the bundles delivered from a binder, shock, firmly compress the shock and deposit it on the ground with its base spread so that the shock will stand.

Another obj ect is to provide a machine ot this character under constant control ot the operator seated on the binder, there being means whereby the operator can control the time oi depositing the shocks, whereby the shocks may be set in windrows, all other operations being automatic.

Another object is to provide a machine which will hold any bundles delivered from the binder pending the formation and dcpositing ot these shocks.

ilinother object is to provide a shocking machinehaving a shock former the sides ot' which constitute shoclr compressino` means, the base ot' the shoclr former operating to spread the butt end of the shocl prior to depositing the same on the ground, the ezitcnt to which the base oi the shock is spread depending solely upon the length oi the shock and not upon the. number ot bundles constituting the shock.

rlnother object is to provide ei'iilcient means for keeping the bundles parallel s they are being deposited in the shoclt 'toi-mer, this means neverthel permitting the bundles to spread ont against the sides oit tho shoclt former so as not reduce the capacity oi the shcon formeny means being employed for l-zeeping the butts oit the hun simple and torni them into a dles out ot contact with the supporting and tornier from the deposited shock withoutl danger oi' pulling the shock over on its side.

With the foregoing and other objects in view, which will al pear as the description proceeds the invention resides in the combination and arrangement ot partsand inthe details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereinl disclosed can bemade within the scope of what is claimed, without departing from the spirit' of the invention.

.ln the accompanying drawings the preerred form olf the invention has been shown.

ln said drawings Figure l is a front elevation of al shocking machine embodying the present improve ments, the shock former being shown elevated to bundle receiving position, some of the parts of the machine being brolren away.

certain oi the l `tion 3 of said member. liooselymoi this proiecting portion of the shaft 9 Fig. 8 is an elevation of the outer side of the machine with the parts in the positions shown iii F ig. 7, the lever stop being shown in section.

F ig. 9 is a View showing diagrammatically a cross section through the shock former in bundle receiving position and the arrange nient or" the centering cables for holding the bundles parallel.

Fig. l() is a section through one ,ot the winding drums.

Referring to the figures by characters ot reference i. designates .a portion oi the iranie or" a binder and secured to ano extending outwardly and upwardly from this portion ot the .trame are 'iront and rear bars l and 2 merging into vertical nieml ers 3 and respectively which, in turn, are proi/'ided at their upper endsj withV horizontal portions 5 and 6. These bars with their upwardlyand horizontally extended portions constitute the upstanding frame of the machine forming the present invention and the said bars may be connected wherever desired by cross members thus to Jiiorni a rigid structure. The front horizontal portion 5 has its free end curved rearwardly indi cated at 5a while the rear horizontal portion 6 is shorter than the portion 5 as shown parN ticularly in Figs. 2 and 7 The :trame made up or" the bars l an( may be suitably connected to the binder .Y y braces 7 and which braces are preferably i tached to the bars l and 2 close to the standing portions 3 and Ll. 'lhoV pn drive shaft B of the binder is arrai ,l along the portion i of the iframe and supported above the shaft and vsaid portion is the deck C oiithe binder eXtendir-g` under the shaft l) of a kicker arm ll of a binder.

Bearings v8 are attached to the upstanding` portions 3 l of the frame members andV journaled in these bearings is a sha1-t 9V to which are keyed sprocsets @ne end of this shaft projects beyond the Yframe member l and is journeled in a bracket ll secured to the upstanding Y gear l2 formed with or secured to a sprocket 137 this sprocket being provided with a clutch member M. i chain is adapten to transmit motion to the sprocket i3 from small sprocket i6 secured to the pitman drive shaft l.

Engaging the sprockets l() are elevator chains l? having outstanding Ylingers lt?, these chainsbeing extended vertically from the sprockets l() upwardly to sprockets l9 mounted on the uppereiids oi the 'vertical portions 3 and 1l and being then extended laterally to sprockets 2O secured to a transverse shaft 2l mounted on the horizontal portions 5 and Said chains are then ez*- tended over sprockets 22 arranged under trie horizontal portions 5 and 6 and thence downwardly to the sprockets 10. Thus it will be seen that the fingers i8 will be brought successively to position beyond the vertical portions and d so that they will more upwardly to the upper ends ot said portion and then horizontally until they reach the sprockets 20 whereupon the lingers will more back to their initial positions, passing between the sprockets 22.

A sheet metal plate 23 is secured te the vertical portions S and e of the inembers and extends from the upper ends thereof downwardly to a point above the shziit 9 where the plate is curved downwardly and outwardly to tori/n a trough 2e, the lower end of the plate 23 being fastened to and under the deck C of tl e binder. This plate is slotted longituoi :illy as indicated :it 25 to permit the fingers 18 to travel Vertb cally between the sprockets l0 and i9.

Guide rods 26 extend from t.lo shaltA and upwarr lT7 parallel with the vertical portions 3 and e or' the trame members, the upper ends of these rods being bowed over the f space betweentlie frame members-as shown at 27 and haviiigtheir tree ends proicctii downwardly into said space. Thus it trough 2l and there be engaged by the kicker arms E which will direct hein into the paths oit the lingers 18. Vlhese lingers, which are moved upwardly withthe chains l? when the shaft 9 is rotated, will convey the bundles upwardly between the plate 23 and the guide rods 26 and carry said bundles r the sprockets 19 and V20 and deliver them into the space between the frame menibei l and 2.

sheet metal plate 28 is secured to the upstfinding portion 3 and the horizontal portion 5 of the front frame niei'iibor l but the side portion of this plate 28 is discoir nected from the curved portion ot the traine member so that said side portion i'rec to flex toward or from said curved plc-rtion as shown particularly in and T.

clournaled wit-hmL the upstandiiig portions and 1l of the frame members l and 2 and above and parallel with the shaft 9, is a shalt 29 one end portion ci' which projects forwardly and is journaled in the iracket ll. 'ioosely mounted on this shaft 29 and close to the upstanding portion 3 is a drum 30 and arranged at one end ot the drum is a ratchet wheel 3l which is key d to the A pawl 32 is pivotally connected to the upstanding portion 3 and iiormallyreiigages the ratchet wheel 3l to hold it against rotation in one direction. Arranged with in the drum 30' is a coiled spring 33 and one end of this spring is secured to the drum 30 while the other end is secured to the ratchet wheel 31. Thus it willbe seen that when i ji pivot bolt 49 the drum 8() is rotated in one direction while the ratchet, wheel 3l is being held against rotation, the coiled spring 83 will be placed under increased tension.

Loosely mounted on the shaft 29 is a gear 84 which constantly meshes with the gear l2 and has a clutch member 85. Secured on the shaft 29 is a clutch member 36 and another clutch member 87 is severed on the shaft 9.l These two clutch members are mounted for rotation within the end portions of a lever 38 and springs 39 and 46 are mounted on the shafts 29 and 9 respectively and bear at their forward ends against the bracket 1l and at their other ends against the lever 38. A stop 4l is engaged by the lever 38 at a point above the center thereof, said lever being pressed against the stop by the two springs 39 and 40. A latch lever 42 is pivotally connected to the lower portion of the bracket 11 and is adapted, when the lower end ot the lever 38 is pulled away from chain 15, to engage said lower end and thus hold the lever against the action of spring 40 while, Vat the saine time, the clutch member 36 will be t-.hiited into engagement with the clutch member under the action of the spring 89, which presses the lever against stop 41 which thus constitutes a ulcrum.

A lever 48 is mounted on the bracket. 1l and one arm of this lever is connected by a rod 44 to an intermediate portion of the lever 68. The other arm of lever is connected by a cable 45 to an actuating cable 46 which is connected to the pawl 32 and is adapted to be operated by the occupant of the binder. ln other words when this cable 46 ispulled by the operator, the pawl 82 will be disengaged from ratchet wheel 81 and lever 48 will be shifted so as to pull the lever 38 out et its normal position.

Pivotally connected to the portion A et the binder frame at 47 is a laterally extending tiltable trame 47 extending under the space between the `frame members l and 2 and preferably substantially triangular in outline, the outer or .free end ot this tilt-able trame being formed with a bearing plate is extended through the plate and engages a turn table 50 which is semicircular and has an stan. ng seinicircular lflange 51 provided, Lts outer tace, 'with a groove 52. Parallel .i tanding side flanges are formed on Y table and they constitute bearings 'tor t oss rod 54. Journaled on the turn table with its periphery ilush with one end of the grooved flange 5l is a pulley 55 and journaled between brackets 56 on the turn table and close to the semicircular end ot' said turn table a pulley 57 mounted to rotate about a substantially horizontal axis disposed at right angles to the side flanges 53. rliltably mounted on the pivot rod 54 are bea ri n extending some distance beyond the semicircular end of the turn table. The tree ends of the side members 58 are provided with upstandine" arms 59 at right angles thereto, there being suitable connections between` the side members 58 and 59 as indicated at 60 whereby a rigid tiltable trame is provided.

phaurnaled upon the lower portions of the arms 59 are sleeves 61 each having oppositely extending tongues 62 and 63. Fixedly attached tothe tongues 63by rivets 68 (see 4) are` the flanges ot bars 64 which extend over the turn table 50and some distance beyond the pivot rod 54 where these bars merge, along curved lines, into tines 65 constituting the middle members ot the bottom of the shock former. To the outer sides of these bars 64, at the fastened ends thereof are attached additional bars 66 which likewise merge along curved lines to tines which are substantially parallel with the tines 65 andV which have been indicated at 67.` These tines 65 and 67 are so proportioned and positioned that, when the parts are in shock receiving` position as illustrated tor example in Figs. l, 2 and 3 said tines will extend close to and upwardly along the front face of the plate 28.

Pivotally connected to each ot' the tongues 62 is a lever, one ot these levers being indicated at 68 and the other at 69. The lever 68 is formed ot spaced bars connected together as shown particularly in Fig. 6, these bars extending along the upper and lower faces of the tongue 62. The lever 69, however, is formed in a single bar having a forked end 7 O which straddles and is pivotally connected to the other tongue 62. The lever 69'eXtends between the bars of lever 68 and is pivotally connected thereto as indicated at 71 and arranged on the tree ends of the two levers 68 and 69 are stop pins 70 to limit the swinging movement of the levers relative to each other in one direction. pulley 76 is carried by the lever 69 close to its pivot 7l.

Journaledupon the side members 58 so as to rotate thereon are sleeves 74 having outstanding bearings 75. In these bearings are journaled upstanding shafts 76 limited in their rotation by stop pins 77 adapted to come against stop lugs 78 depending` trom the bearings 75.

Extending toward each other from the llO shaft v76 are arms 79 pivotally and slidably v is attached to the arms 88 and 85 and serve to limit the swinging movement ot said arms in one direction. A pulley V88 is connected to one or the arms, 85, close toits pivot 84 and additional pulleys 89 are mounted on the bars 64 close to the tongues 63.

A transverse shaft 90 is journaled in the arms 59 above the sleeves 61 and loosely mounted on this shaft so as to rotate, is a drum 91. il ratchet wheel 92 is keyed or otherwise secured to the shaft 90 at one end of the drum 91 ranged in the drum. @ne end of this spring the shaft 90 while the other end is attached to the drum. A pawl 94 normally engages the ratchet wheel 92. Pim otally attached to the pawl 94 is one end of a rod 95. This rod extends between the intermediate bars 64 of the bottom of the shock former and is connected to a lever 96 which is pivotally attached, between its ends, to one ot the tines 65, one end of this lever normally projecting outwardlybeyond the tines 65 as shown particularly in F ig. 3.

Secured to the drum 91 and wound in opposite directions thereon are cables 97 and 98.` rThe cable 97 extends partly around one et the pulleys 89 from drum 91 thence into engagement with the two pulleys82, and the other pulley 89 and is attached, at one end, to one of the tongues 63. Thus when said cable'97 is wound upon the drum it will pullA onthe pulleys 82 and causey ,he shafts 79 to swing toward each other. The cable 98 extends from the drum 91 to the pulley 88 thence to pulley 73 trom which it extends over apulley 99 which is journaled on a rod 100 connecting the sides 58 of the tilt-able frame and the shock former. F rom this pulley 99 the cable 98 extends downwardly under the pulley 57 and thence 104 constituting the sides of the shock former. lllhen the shock iormer is in its normal or shoclrV receiving position these rods lie in vertical planes and secured to the upper endsto certain ot the rods are cables 105 which extend downwardly around pulleys 106 attached to the lower ends of said rods thence to springs 107 attached to the intermediate portions of the rods.

A spring 108 extends under lthe side vmemand a coiled spring 93 is ar-i Y into engagement with pulley 55, under a pulley 101 on'V the `tiltable sup :pasarse i of the shock former normally 'in the position illustrated in Figs. 1, 2 and 3 and with the sides oi the shoclr former extended upwardly. side of the turn table remote trom the pulley 55 and' connected to the saine side of the turn table is one end of thecable 111 which extends within the groove 52 in flange 51 toward the binder, one

and thence laterally end of theV cable kbeing secured to a heavy coiled spring 112 which is secured to the trame oi' the binder as shown for example in l? ig. 1. Y

The tiltable supporting frame 47 of" the machine is provided with a keeper 113 on one side thereof and which is normally engaged by a latch nec'ted to the frame member 1. A spring 115 serves to hold the latch lever normally in engagement with its lreepenthus to support the tiltable supporting frame in raised position. A releasing lever 116 is pivotally mounted, as at 117, upon the tiltable sup- 1sowing `frame 47 and is adapted, when laterally, in one direction, to press .i st the latch 114 and disengageV it from its 1nee-per 113, thus 'to permit the tiltable supporting frame 47 to swing downwardly.

El. stop 118 is arranged on the tiltable supporting frame 47, where it will be engaged by the latch lever 110 when the shock former is moved to delivering position, as shown in TEig. 7

lBivotally mounted on the supporting trame 47 and adjacent the turn table is a lever 119 having a short arm 120 which eX tends toward the turn table so that when said turn table is moved to bring the shock former to bundle receivingV position, the lever 119 will be actuated against the action oi a spring 121.. A cable 122 is connected to the long arm of this lever 119 and extends to the latch lever Attached to the lever 68 is one end of a rod 123. The other end et this rod is conect-ed to the upper is pivotally mounted en the rod 100 cari af'- ing the pulley 99. lever is adapted to rest upon theV turn table 50 under normal conditions. Y

irom the foregoing description it will be apparent that when the shock former is in bundle Vreceiving position the tines 65 and 67 are extended vertically in front of the plates This lever 110 is located at that end of a lever 124 which The lower end et thisV lever 114 pivotally con- Y 28 and the side rods 10d of the shock former are disposed in vertical planes with their upper ends spread al art se that the cables 105 are extended downwardly along cenverging lines, as shown particularljg.`- in 9, this arrangement ci the reds 1011 being due to the tact that the shafts 76 are normally swung away from each other. lConsequently as the app: ratuf: herein described travels alongside or" the binder and the bundles are discharged from the binder, said bundles will be elevated as hereinbefore described and dropped into the space between the downwardly converging cables 105. rl`hese`cables will be held normally taut by the springs 107 and will maintain the bundles parallel whether or net they completely lill the space between the rods 104. ils the bundles pile up between the cables 105 said cables will. bend eutmirdly toward the rods 104i. lt is to be miderst-ood of course that as the lever freely mounted the spring L10 will shift the clutch member 87 into engagement with the clutch member 11i so that motion is normally transmitted from the pitman drive shaft through chain 15 to the shaft 9 and the elevating chains thereon. The distance between the stop 41 and the clutch member 87 is greater than that from the stop L11 to the clutch member 36 and the spring l0 being stronger than the spring 89 it will be obvious that the clutch members 37 and 111 will be normally in engagement with each other. The cable 98 is wound on the druni 30 and said drum is held against rotation by the pawl lVith the cable 98 thus taken up, the toggle made up of the levers 68 and 69 is held extended with the tongues G2 pushed apart and the tongues 65% pressed toward each other, thereby holding the bars 64 parallel or closed toward each other. The taut cable 98 also holds the toggle made up ot arms 83 and 85 extended, thus to press the upper ends ot the shaft 78 apart to maintain. the upper ends of the rods 1.04 spaced apart so that the opposed sets of rods 104.- will be spaced equally thereby to allow the bundles to fall between said upper ends. .Attention `is called to the tact that when the bundles are deposited in the shock Vfermer their butt ends will not engage the tines 65 and 57 but will, instead, engage the metal Yplate 28 and thus be free to spread withcut interference.,

After a desired number oit bundles have been deposited in the shock `former in the manner described, the operator pulls upon the cable 1G. rlhis action causes the cable 45 and lever d3 to pull outwardly on the lever 88, causing said lever to move against the action of its springs 39 and Ll0 until the lower end of said lever is hooked into engagement with the latch lever l2; At the same time the pawl 32 is disengaged from its ratchet wheel7 thereby releasing the drum 30 and the cable 98. The release of the cable will result in the release of the arms 83 and S5 and, consequently, the upper ends o the shafts 76 will be allowed to swing toy"ard each other lor the purpose of conipressing the shock. fllhis shitting ot the upper ends out the shafts 76 toward each other will be produced by the spring 98 which will promptly wind up the cable 9T on the drum 91 at the same time taking up slack in the cable 98. its the paid out cable 98 relieves the turn table oil the restraining influence or said cable, it wil be obvious that as soon as said cable begins te unwind from the drum 30, the spring 112, which is normally under tensioinwill pull on cable 111 and `cause said cable to unwind from the arcuate end of the turn table V50, thus causing said turn table to swing horizontally through approximately 180 degrees until stepped by the latch lever 110 coming against the stop projection 118 as shown in Fig. 7.

'ils the shock is held under compression during this turning of the table 50, due to the pull of the cable 97 upon the pulleys 82 and the resultant binding ot the rods 10d against opposed portions of the shock, it will be obvious that as the table is rotated the butt end of the shock will be moved away from the sheet metal plate 28 and pass the flexible portion of said sheet. n lter the shoclr former has thus been rotated the butt end of the shoclr, instead of resting on a metal plate 28 will come against the tines 65 and 67 and will be extended rearwardly from the machine. lNhen the latch lever 110 contacts with stop 118 upon the completion of the rotation of the turn table 507 the tiltable frame of the shock former will be released andthe weight of the butt end olf the shock will cause the entire tiltable iii-anne ot the shock former to swing downwardly about the rod 541 as a pivot, bringing the tines 65 and 67 close to the ground. is the shock former begins to swing downwardly in this manner the lever 12d which up till then has been held against movement by the table 50 and has conse quently held the levers 68 and G9 locked, will be :tree to move with the result that the sleeves 61 will be released and the 'tongues and bars 64e left free to swing apart Jfor the purpose of spreading the butt end of the shock resting on them. Simultaneously with the foregoing operation the links will releasel the shafts 76 which will thus be tree to rotate in their bearings.,V causing the lower reds 1041 to shift outwardly from the shock. The tines 65 and 67 will also move apart as heretofore described, thus to maintain the shock spread against the lower rods 104:. @bviously this outward movement o the lower rods 104 is limited by the stop pins 77 and lugs 78. Likewise during this operation the spring 93, which is under tension, serves to keep a` strong pull upon the cable 97 through the V-ing portions of the tines 65 strike the free Y from under the standing Vreleases the held cable46 and as the lower it will be apparent that'when end of the releasing lever 116 and cause said lever to push against latch 114 and disengage it from its keeper 113. Consequently the tiltable supporting frame 417 will drop` so that the tines and 67 will thus be permitted to rest on the ground. the tines touch the ground the projecting end of the lever 96 will strike the ground and cause the cable 95 to pull on the pawl 911, thereby releasing the spring 93 and drum 91 so that the cable 97 will'be relieved lfrom the pull exerted by the spring. rl`his will result in stopping the compressing and spreading action o'l the apparatus and spring 108 will swing the shafts 7 6 apart, thus to spread the shock holder suliciently to allow the free withdrawal thereof from the standc ing shock.

6? have pulled out shock the operator After the'tines 65 and the latch 42 this cable is lever 38 will end of the lever 38 is held by released the upper end of the `move under the action of the spring 39 to bring the clutch member 36 into engagement with Clutch member 35, thus causing the cable y98 to wind upon the drum 30. This will result in resetting the levers 68 and 69 and the lever 81. 1t will also bring the tiltable frame of the shock former back to its normal position with its sides 58 resting on the turn table where it will be locked by the latch 110. When the turn table is swung to itsdiscliarging position under the action ofthe cable 111, the cable 98 becomes seated `in the groove 52 in flange 51 and consequently, during` the winding Y of vthe cable 98 the turn table will be moved back to its initial position against the action oi" the spring 112`until the push or thrust of the turntable 50 against the end 120 of lever 119 is suilcient to overcome the spring 121.V As soon as this springisovercome the cable 122 will disengage the latch lever L12 from the lever 38 and allow saidlever 38 to move bodily until it engages the stop 41 which will then act as a fulcrum and result in disengaging the clutchmember 36 from the clutch member 35. At the saine time the'other clutch members 111 and 3? will be placed in engagement with the result that rotation of the drum 30 will be stopped and actuation of the elevator will commence. 1t will be apparent that the amount of winding of the spring 93 will depend upon the pull exerted by the spring 121.-
